What do you think about the combinations?
What fins do I need (50cm and 44cm Drake Venom a delivered with the boards)?
What about the sail sizes. Too big jumps? Maybe 6,7 insteed of 6.2?
What about the boards? From 141 to 121. Ok?

Hi,
I think the combination F141 + 10.0 +50cm Fin and F121 + 7.7 + 44cm Fin should do well, but the 6.2 is in my opinion too small for your boards. So for Highwind you should take the F93 and 36cm Fin.
Change volume of the boards ? Are you crazy ?

I used to own a F122 and used it with sails 7.8, 6.7 and 5.8 although if the conditions were a little rough the 5.8 felt a little small for my 85Kg. I used a 42cm fin for the 7.8 and a 36 for the 6.7 but as you are a little bigger I would perhaps go 44 for the 7.7 and 36 for the 6.2
